Private Beta — Now Accepting Testers
Every investor has two risk profiles: the mathematical risk of your portfolio, and the psychological risk of your behavior. Brokerages measure the first one. Gertie measures the second — building a behavioral picture of who you actually are as an investor.

Most investors don't lose money because they picked the wrong stocks.
They lose it because they sold in a panic. Bought on FOMO. Held a loser too long, waiting for it to come back.
Cognitive biases cost investors 1–2% in returns every year. Over a lifetime, that's not a rounding error.
The hard part isn't knowing this. Most investors already do. The hard part is catching yourself in the moment — before you click the button.
That's what Gertie is for.
How It Works
When you're thinking about a decision — selling a position, buying into something new, checking your portfolio for the fifth time today — you talk to Gertie. She listens. She asks questions. She helps you see what's actually driving the urge.
She never tells you what to do. She asks things like:
"Has your thesis changed, or just the price?"
"Is this a plan, or a reaction?"
"What would you tell a friend in this situation?"
Over time, she learns your patterns — the biases you're most prone to, the situations that trigger reactive decisions — and meets you there, calmly, without judgment.
Loss Aversion
Selling because the pain of a loss feels unbearable — not because anything actually changed.
FOMO
Buying because everyone else seems to be, and sitting out feels worse than jumping in at any price.
Recency Bias
Treating last week's move like it predicts next month's direction.
Anchoring
Fixating on what you paid for something, not what it's worth now.
Confirmation Bias
Only reading the articles that agree with you — and feeling more certain because of it.
Overconfidence
Certainty that feels different from the last time you were certain and it didn't work out.
Disposition Effect
Selling your winners to lock in gains, holding your losers hoping they come back.
Your Behavioral Fingerprint
Not a one-time questionnaire you filled out when you opened your account. A picture that builds over time — from your check-ins, your conversations, your decisions — and updates as you do.
The goal isn't a perfect profile. It's an honest one.
Consistency
How reliably you show up and reflect — even when markets are calm.
Composure
How steady you stay when things get volatile or uncertain.
Discipline
How often your decisions match your stated plan.
Clarity
How clearly you can articulate your reasoning before you act.
Patience
How well you resist the urge to act when waiting is the right move.
Awareness
How well you recognize your own patterns as they're happening.
Your profile reflects patterns — not predictions. It updates as you check in.
Gertie is not a financial advisor. She will never tell you what to buy or sell. She's not a robo-advisor managing your money. She's not trying to replace your broker.
She's the thoughtful friend who asks the questions you should be asking yourself — and remembers the conversation.
If you already suspect your emotions cost you money — and you'd like help catching that in real time — we'd love to have you.
You're on the list. We'll be in touch soon.
